1:方式1:

public static List<String> userList;
    static {
        userList = new LinkedList<String>();
        try {
            **String filePath = TestClient.class.getClassLoader().getResource("users.txt").getPath();**
            **BufferedReader reader = new BufferedReader(new FileReader(new File(filePath)));**
            try {
                String line = null;
                while ((line = reader.readLine()) != null) {
                    userList.add(line);
                }
            } finally {
                reader.close();
            }
        }catch (Exception e){
            e.printStackTrace();
        }
